Standard Electromotive Force of Silver-Silver Chloride Electrode and Related Thermodynamic Quantities in tert-Butyl Alcohol-Water Mixtures (2, 6, and 8 Wt %) between 5-45°

The electromotive force measurements of the cell Pt, H2 (1 atm) | HCl (m) in H2O | | HCl (m), ButOH (x), H2O (y) | AgCl, Ag at nine temperatures in the range 5-45° were used to derive the standard potential of the cell, the activity coefficient of HCI for molalities in the range 0.002-0.1, and the thermodynamic functions, δG°, δH°, and δS0, for the transfer of HCI from water to the respective ferf-butyl alcohol-water mixtures. The standard potential was calculated by a theoretically justified polynomial curve-fitting program and varied with temperature, f, °, according to the equations The molality of the acid ranged from 0.005-0.2 mol kg-1.
